OPERATION
READY Mode
Select Alternate Modes
When the LX-1 Stereo Selector is first powered up, and has lost memory, it defaults to the SAFE
mode. All lights, all channels, LOOP and
MIX will be off In this mode the LX-1 will only respond to a command to enter the READY
mode.
To enter the READY mode, press the READY button on the front panel, or execute a READY
command from the remote control connector. The READY light will light and the LX-1 will now
accept all commands.
The READY mode provides security for those times when all switching is to be disabled. When
used as a master control switcher it may be desirable to set READY off until just before switching
is desired. This feature is useful when each studio has its own selection button. Accidentally
pressing a button will not then switch studios.
In the READY mode channel selection, LOOP and MIX control is possible from the front panel
or from remote locations. Momentary closure on any channel select pin will select that channel
and illuminate the selection status indicators (front panel lights and remote control status).
When the MIX light is off the LX-1 functions as a one-at-a-time input selector. Once a source is
on, further attempts to select that source will have no effect. This is the normal, or SELECT
mode, of operation.
The LX-1 can be programmed for alternate action (press on, press off) in the select mode. This is
accomplished by moving the jumper on 51 on the logic board from SEL to ALT. See figure 6,
page 8, “SELECT ALTERNATE JUMPERS.” This feature is handy when a source needs to be
repeatedly turned on or off while in the SELECT mode.
